Application led March 3, 1916. Serial No. 81,932.

To all whom t may concern:

Be it known that I, CARL V. LUNDIN, a subject of the King of Sweden, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Vault-Lights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to prevent breakage of glass lenses employed in vault lights under the expansion and contraction of the parts of the frame in which the lenses are mounted.

Another object of the invention is to entrap any water that may ind its way between the lenses and the frame, so as to prevent the same from passing below the lenses.

A further object of the invention is to admit of the lens being either tightly or loosely clamped within the frame as desired.

Other objects will appear and be better understood from that embodiment of my invention of which the'followingA is a specification, reference being had to the accompanying drawings forming a part thereof, in which:

Figure 1 is a top plan view. of a section of the vault light, Fig. 2 is a transverse section taken through a portion of the frame. Fig. 3 is a transverse section taken through certain of the glass lenses and through the frame, Fig. 4 is a perspective View of the upper portion of the frame. Fig. 5is a perspective view of the lower portion of the frame, Fig. 6 is a perspective view of an improved lens, Fig. 7 is a perspective view of a gasket to be associated with the lens shown in Fig. 6, so as to prevent breakage of the lens or the passage of water between the lens and the frame.

Referring to the drawings'in detail, the numeral 1 designates a frame composed of an upper section 2 and a lowersection 3, the lower section being formed of parallel spaced metallic strips 4, which strips have alined openings 5 formed therein for the reception of a plurality of strips 6, which extend through the openings 5 in the strips 4 and are disposed at points intermediate the height of the strips 4, as is shown more, particularly in Fig. 5 of the drawings.

Mounted upon the upper sides of the strips' 6.are a plurality of flexible strips 8, preferably formed of rubberl or the like, and upon which rest the lens pieces 9. The lens pieces 9 are preferably of rectangular' Configuration, as shown in Fig. 6 of the drawings, and the upper sides of the lens pieces are provided with raised rectangular portions 10,which are considerably smaller than the main body portion of the lens 9, so as to provide the shoulders 11, the said shoulders being provided with a plurality of intersecting grooves 12, as shown in Fig. 6 of the drawings. Flexible washers or gaskets 13 are adapted to engage around the raised portion 10 on the lens pieces 9, and rest upon the shoulders 11, and the said washers or gaskets 13 are each provided at opposite points with the semicircular cut-out portions 14, which register with semicylindric'al cut-out portions 15 formed in the adjacent sides of the lens piece 9.

The upper sectionQ of the frame is composed of the parallel spaced strips 16, which are providedv with cut-out portions 17, for the reception of a plurality of spaced intersecting strips 18, the said strips 18 having their under sides provided with cut-out portions 19, designed to register with the cutout portions 17 in the strips 16, so as to ad- Amit of the upper and lower sides of the strips 16 and 18 lying flush, the said strips 16 and 18 being held in assembled position by means of the fastening element 20. The upper section 2 of the frame is adapted to be superimposed on the shoulders 11 of the lenses, and by virtue of so connecting the strips 16 and 18 forming the upper section 2, a plurality of rectangular shaped openings 21 are provided which receive the upper raised portion 10 on the lens pieces 9, as shown more particularly in Figs. 1, 2 and 3 of the drawings. The strips forming the upper section 2 causes a tight engagement between the gasket 13 and the adjacent shoulder 11 on the lens body, and, as shown in Fig. 3, the said strips 16 and 18 are spaced slightly from the adjacent sides of the raised portions 10 of the lens body so as to prevent pressure being exerted on' the lens during the expansion and contraction of the said strips.

A plurality of bolts 22 extend through openings 23 in the strips 18 of the upper section 2, and through the semi-circular cutloo out portion 14: in the washers or gaskets 13, and the semicylindrical cut-out portions 15 in the sides oi' the adjacent lens body and through openings in the lower strip 6 of the lower section 3, the lower ends of the bolts being threaded for the reception of nuts 25, which are adjustable against the under sides of the strip 6 of the lower section. By virtue oi' the connection between the lens body 9 and the bolt 22 the lens will be held against horizontal movement and the clamping engagement between the upper section 2 and lens can be regulated by the adjustment of the nut 25 on the lower end of the bolt 22.

The grooves 12 forming the shoulders 11 on the lens body 9 will serve to enti-ap any water which lies between the raised portions 10 on the upper side of the lens body and the adjacent strips 16 and 18 forming the upper section 2 of the frame, and thereby prevent any liquid from passing beneath the lens body 9. The upper surfaces of the raised portions 10 are disposed slightly below the upper sides of the strips 1G and 18 on the upper section 2 so as to prevent injury being done to the said raised portions.

Having thus described the invention what is claimed as new, is:

1. A vault light comprising a frame having an upper and lower section, each of the sections being formed of intersecting strips, glass bodies mounted on certain of the strips forming the lower section of the frame and having portions extending into the spaces between the strips forming the upper section of the frame, said glass body having the upper sides provided with grooves, and fastening means extending through the upper and lower sides of the frame and engaging the glass bodies.

2. A vault light comprising a frame having an upper and lower section, each being formed of intersecting strips, the strips forming the upper and lower sections having alined. openings therein, glass bodies mounted on the strips forming the lower section and having portions extending into the spaces between the strips forming the upper section, the said glass bodies having cut-out portions therein registering with the openings in the strip in the upper and lower sections, and bolts extending through the openings in the strips and through the cutout portions in the glass body, and nuts turned on the bolts.

3. In a vault light, the combination with a frame Jformed of an upper and lower section consisting oi' intersecting strips, of a plurality of transparent bodies mounted on the strips forming the lower section and having their upper sides provided with reduced portions extending into the spaces between the strips forming the upper section, the said upper sides of the transparent bodies having grooves therein, and ilexible elements overlying the grooves and inter` posed between the upper sides of the glass bodies and the strips forming the upper section of the frame.

In testimony whereof I ailix my signature in presence of two witnesses.

CARL V. LUN DIN.
